Answer = 127 degrees
Firstly, find out how many degrees in total are in the polygon.
(n stands for number of sides)
(n - 2) x 180
(6 - 2) x 180 = 720
Afterwards, subtract that amount by all the given angles.
720 - 112 - 133 - 128 - 100 - 120 = 127 degrees

1 : 100,000
Because there are 100cm in a m and 1000m in a km
100 x 1000 = 100,000
If you’re simplifying it’s 100x^2+200x+5
Answer: x=2 and y=-3
